Abstract

Disclosed are novel tetrachloro-butyl secondary phosphites which are the reaction product of 4,4,4-trichloro-1,2-epoxybutane or 2,4,4,4-tetrachlorobutanol with a phosphorus trihalide. These compounds are useful as flame retardant additives in plastic resin compositions.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
       1. A tetrachloro-butyl secondary phosphite having the formula: ##STR4## wherein R is selected from alkyl of 1 to about 20 carbon atoms, 2-haloalkyl of about 2 to about 8 carbon atoms, alkaryl, aryl, halogenated aryl, and arylalkyl. 
     
     
       2. The compound of claim 1 wherein R is 2,4,4,4-tetrachlorobutyl.
